... 10◦–16◦despite the gusting of the wind. The stoss slope of the ripple lies in the range 8◦–10◦[227]. The lee slope is composed of a short straight section near the crest at anangle of about 30◦–34◦to ... on the dynamical behaviour of real sandpile surfaces.Finally, we present as an example of the use of these equations, a study of the dynamics of aeolian sand ripples [216].11.3 Case A: the ... below.11.3.2 Some caveatsWe realise from the above that the interface h is smoothed because of the action of the flow term which penalises the sustenance of finite gradients ∇h in Eq. (11.4).However,...
